<< But ALL the bass strings were far FLATTER than the steel strings. There were about 5 double unisons in the tenor section so this was over inherent over the break. What gives? Different string manufacturer? >> Greetings, I would suggest that the bass strings were not settled when the factory sent the piano out, and their hitch pin coils still contained a lot of "slack" in comparison to the plain wire. try the following. After a piano has been strung and tuned for a year, take a pair of pliars and grasp the tight part of a bass string hitch pin coil. Lightly wiggle or twist it back and forth,then check the pitch. It is not uncommon to see a 15 cent drop in the bass strings, even after a year of being near pitch. Regards, Ed Foote RPT
